  • ORDER CODE

Decentralised supply and extract air units ventilate the room and cover the cooling and heating load in accordance with the technical data.
An EC centrifugal fan takes in the outdoor air which then flows through the motorised shut-off damper and the outdoor air filter.
The outdoor air then flows through the rotary heat recovery unit, which can be switched off in energy efficient operating situations.
Before the supply air flows into the room like displacement air, it is heated or cooled in the heat exchanger if required (optional for 4-pipe units).
The extract air first passes through the extract air filter, then flows through the heat recovery unit, the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air.
If the indoor air quality is sufficient, the FSL-CONTROL III control system switches to energy-efficient secondary air mode by closing the outdoor air dampers.
The control system compares the indoor air quality setpoint value to the actual values measured at the CO2 sensor and switches automatically between outdoor air and secondary air operation..
In case of a power failure, the outdoor air and exhaust air dampers are closed to ensure fire protection, frost protection and to avoid draughts. This is ensured by a capacitor in each actuator.
Near the external wall, the supply air is discharged into the room with a medium velocity between 0.5 and 0.8 m/s. Due to the induction effect, the supply air velocity is rapidly reduced so that, in cooling mode, the supply air displaces the room air over the entire floor area.

Near heat sources such as people or equipment, a lift current is formed by natural convection, so that the air is exchanged primarily in these areas.

Optional equipment to increase the comfort of the FSL-CONTROL III:



TROX room control panels for FSL-CONTROL III



At least one room temperature signal is required per room. There are several variants of TROX room control panels available, optionally with or without selector switch. Additionally, we offer a room temperature sensor RTF without control elements. Alternative on-site room control panels must be connected via bus communication.





 



Digital room control panels for surface mounting:



For operation and adjustment of the ventilation units.







 



Control panels with selector switch for surface mounting:



Control panel with selector switch, type Thermokon, for surface mounting:







 



Control panels without selector switch for surface mounting:

Version as SLAVE DEVICE



Identical to the MASTER DEVICE, as described above, but with the following deviations:



  • No room air quality measurement in the unit
  • No connection option for room control panels
  • No outdoor temperature detection in the outdoor air
  • No connection to on-site bus communication possible
  • Pre-assembled self-sufficient control system for decentralised façade ventilation units in SLAVE construction


Commissioning of the decentralised ventilation units

Commissioning/parameterisation of the decentralised ventilation units without integration into an on-site MCE/BACS



  • Visual inspection of the device connections on site for compliance with the respective installation specifications from the installation and configuration instructions: air connections, heating/cooling connection, electrical connections, integration into the installed outer casing, connections of external components
  • Checking and, if necessary, adapting the project parameters pre-set in the factory with regard to customer-specific adaptations
  • Functional test of the individual components (control elements, fans, valves, dampers, sensors)
  • Checking the project-specific control functions including any special functions such as volt-free switch contacts
  • Documentation of the device settings and service work in a service report. The service report must be signed by your company or representative as the client.
  • Invoicing is done as a flat rate, derived from the number of units and distance.
